public class ProblemHandlerWrapper extends java.lang.Object implements ProblemHandler
ProblemHandler
s, convenient for subclassing to
decorate/intercept an existing problem handler instance.Modifier and Type | Class and Description |
---|---|
static class |
ProblemHandlerWrapper.Tee
Like the UNIX tool tee, a Tee forks problem handling
in two directions, that is, to two other problem-handler instances.

Constructor and Description |
---|
ProblemHandlerWrapper(ProblemHandler delegate)
Initializes me with the problem-handler to which I delegate.
|
Modifier and Type | Method and Description |
---|---|
void |
analyzerProblem(ProblemHandler.Severity problemSeverity,
java.lang.String problemMessage,
java.lang.String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking
handleProblem
with a analyzerProblem processing phase. |
void |
beginParse()
Notifies me that parsing is about to begin, from which I may receive
problems.
|
void |
beginValidation()
Notifies me that validation is about to begin, from which I may receive
problems.
|
void |
endParse()
Notifies me that parsing has completed, and I will get no further
problems in this session.
|
void |
endValidation()
Notifies me that validation has completed, and I will get no further
problems in this session.
|
void |
flush(org.eclipse.emf.common.util.Monitor monitor)
Flush all problems to their recipient.
|
int |
getErrorReportLineOffset()
Queries the line offset for reporting errors.
|
AbstractParser |
getParser()
Queries the parser from which I obtain source tokens and text.
|
void |
handleProblem(ProblemHandler.Severity problemSeverity,
ProblemHandler.Phase processingPhase,
java.lang.String problemMessage,
java.lang.String processingContext,
int startOffset,
int endOffset)
Handle a problem of problemSeverity that has arisen during processingPhase and which
is explained by problemMessage optionally clarified, if non-null, by processingContext,
and if non-negative by the startOffset and endOffset character indexes in the parsing stream.
|
void |
lexerProblem(ProblemHandler.Severity problemSeverity,
java.lang.String problemMessage,
java.lang.String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking
handleProblem
with a lexerProblem processing phase. |
void |
parserProblem(ProblemHandler.Severity problemSeverity,
java.lang.String problemMessage,
java.lang.String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking
handleProblem
with a parserProblem processing phase. |
void |
setErrorReportLineOffset(int offset)
Sets the line offset for reporting errors.
|
void |
setParser(AbstractParser parser)
Define the syntactic parser from which source tokens and text may be obtained.
|
void |
utilityProblem(ProblemHandler.Severity problemSeverity,
java.lang.String problemMessage,
java.lang.String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking
handleProblem
with a utilityProblem processing phase. |
void |
validatorProblem(ProblemHandler.Severity problemSeverity,
java.lang.String problemMessage,
java.lang.String processingContext,
int startOffset,
int endOffset)
Convenience method typically invoking
handleProblem
with a validatorProblem processing phase. |
